BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 769,692, dated September 13, 1904.

Application filed April 30, 1902. Serial No. 105,253. (No model.)

To all whom, it may concern:

Be it known that I, FREDERICK G. DAVIES, a citizen of the United States, residing at North Tonawanda, in the county of Niagara and State of New York, have invented new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to a baling-press which is more particularly designed for baling the shavings of planing-mills and similar material.

The objects of this invention are to improve the actuating mechanism of the plunger, to provide a locking device for the cover of the presser box or chamber whereby the cover is automatically locked upon closing the same and which can be readily unlocked for opening the cover, and to provide improved means ligor delivering the shavings to the presser- In the accompanying drawings, consisting of two sheets, Figure 1 is a longitudinal section of a baling-press provided with my improvements. Fig. 2 is a fragmentary sectional top plan view of the conveyer mechanism whereby the shavings are fed to the presser-box and the surplus is carried away. Fig. 3 is a horizontal section in line 3 3, Fig. 1. Fig. 4 is a fragmentary front elevation, on an enlarged scale, of the baling-press, showing the position of the cover-locking mechanism when the cover is open. Fig. 5 is a sectional view of the same, showing the position of the locking mechanism when the cover is closed. Fig. 6 is a fragmentary longitudinal section in line 6 6, Fig. 5.

Like letters of reference refer to like parts in the several figures.

A represents the main frame of the balingpress, and B the pressing box or chamber, having a movable top or cover C at its upper end and a plunger or follower D in its lower part, whereby the shavings in the presserbox are compressed preparatory to placing the tie wires or bands around the same in a well-known manner. The plunger is reciprocated vertically in the pressing-box by a ram or engine consisting, essentially, of a cylinder- E, arranged vertically below the presser-box, a piston 6, arranged in the cylinder, and a rod 6, connecting the piston and plunger and pass' ing through the upper head of the cylinder. Steam or other pressure medium is conductedinto the space in the cylinder below the piston by a pipe F, having a valve f. The spent steam is-discharged from the cylinder by an exhaust-pipe'G, containing a valve .9. Upon closing the exhaust-valve g and opening the pressure-valve steam is admitted into the lower part of the cylinder, thereby raising the piston and plunger and compressing the shavings in the box. Upon closing the pressurevalve and opening the exhaust-valve the spent steam is permitted to escape and the piston and plunger descend by gravity.

H represents a vent-pipe which contains a valve 7L and whereby the space in the cylinder above the piston is placed in communication with the atmosphere. By opening the regulating-valve it more or less the escape of the air from the upper end of the cylinder during the upward movement of the piston and the admission of air into the same end of the cylinder during the downward movement of the piston may be cushioned so as to prevent sudden or quick action of the piston, thereby avoiding straining or racking of the press and also enabling the attendants to conveniently remove the finished bale and prepare the press for the next following bale.

The top or cover G is pivotally connected at its rear end to the press-frame by hinges 0 0, so that the cover can be turned vertically for opening and closing the top of the presserbox. The cover is preferably counterbalanced by a weight 0, attached to arms 0 projecting rearwardly from the cover. Upon closing the cover over the top of the presserbox the same is held in place by a locking device, which is constructed as follows:

I I represent two coupling-lugs, which project upwardly from opposite sides of the front part of the main frame and which are adapted to enter sockets in the opposing front part of the cover. Each socketis formed partly by the space j between the upright flanges of two angle-irons J J, secured upon the'cover, and partly by openings 3'' formed in the base-flange of one of said angle-irons and in the cover in line with the space as shown in Figs. 5 and 6.

' the presser-box, as shown in Fig. 5.

K K represent coupling or looking bolts, which are movable transversely in guides on the coverand each of which is adapted to pass at its outer end through corresponding openings in the upright walls of one of the sockets and the corresponding couplinglug I, thereby locking the cover over the inlet of Each locking-bolt is yieldingly held in its operative position by a spring Z, interposed between a shoulder on the bolt and a standard Z, in which the inner end of the boltis guided. The inner ends of the bolts are connected by links m m with opposite arms of a hand-lever M, which is pivoted on an angle-iron on the cover. Upon turning the hand-lever in the direction of the arrow, Fig. 5, both bolts are withdrawn from the lugs I I of the main frame, thereby unlocking the cover, so that the same can be raised for opening the top of the box, as shown in Fig. 4. Each of the locking-bolts is held. in its retracted position while the cover is raised from the presserbox by a detent consisting of an arm N, pivoted at its inner end on the standard Z and having a'depending tooth or pawl n, which is adapted to engage in a notch n in the upper side of the companion locking-bolt. The outer end of thedetent-trm projects over the angle-irons J J and has an opening which receives a guide-rod" O, projecting upwardly from the outer angle-iron J. The detent is depressed into its operative position by means of a spring 0, interposed between the upper side of its arm and a screw-nut 0 on the upper end of theguide-rod 0.

The coupling-lugs-I 1 are of such height thatwhen they fully enter the sockets of the cover they project above the angle-irons J J and lift the detents out of engagement from the locking-bolts. While the cover is open the locking-bolts are held in their retracted positionoutside of the path of the couplinglugs I by the detents, which are depressed and engage their pawls with the notches of the bolts, as shown in Fig. 4. While the box is thus open and the plunger is lowered the box is filledwith shavings or other material to be baled, and then the cover is closed down upon the box, whereby the coupling-lugs enter the sockets of the cover and lift the detents'out of engagement from the bolts, causing the latter to be projected by their springs through the openings in the coupling-lug and the opposite walls of the socket, as shown in Fig. 5, automatically locking the cover upon the presser-box.

After the box has been filled the plunger is raised to'compress the shavings, and the tiewires or bands are applied to the bale. The attendant then turns the hand-lever in the direction of the arrow, Fig. 5, for withdrawing the bolts from the coupling-lugs, and when the bolts have been thus shifted the expansion of the bale causes the cover to be lifted BEST AVAlLABL'E CC? sufiiciently to permit the detents to drop with their pawls into engagement with the notches of the bolts-and hold the same in a retracted position. The cover is now raised so as to fully clear the top of the box to permit the bale to be removed and another charge of loose shavings to be delivered into the box.

It will be observed that the locking device is automatically released by the trip device when the door is closed upon the box and that but a single movementof the hand-lever is required for releasing the cover and holding the locking device in its inoperative position.

The feed mechanism whereby the shavings are delivered to the box is constructed-as follows: P P represent the upper and lower sections of an upright feedespout arranged above the presser-box. The upper receivingsection P of the spout is fixed, and the shavings are delivered into the same by a .conveyer Q, which has its receivin in the lower part of thc room R. The lower delivery-st. spout is pivotally connected at its uppe.

a hinge p with the lower end of the upper Sr.

tion, so that the outlet of the lower section can be swung over the box for delivering shavings into the same, as shown by dotted lines in Fig. 1, or swung to one side of the box for cutting off the feed to the box and permitting the cover to be closed,as shown by full lines in the same figure. The spout is preferably flared and enlarged from its upper inlet end toward its lower outlet end, so thatthe shavings fall away from the inner side of the spout and prevent the same from becoming clogged. The spout-sections are so arranged that the same are both substantially in vertical alinement with the box while feeding shavings to the latter, and the pivotal connection between the sections is so constructed that the lower section swings forwardly frornthe box into an inclined position, in which it is held when not in use by a catch 8, mounted on a stationary support.

As the shavings descend through the spout into the presser-box a blast of dust escapes through the space between the spout and the box, which blast in the absence of any provision to prevent it would blow the dust up wardly into the face of the. attendant. In order to prevent the dust from blowing upwardly, on the outer side of the delivery-section of the spout the latter is provided with a guard-fiange'or shield t, which extends entirely around the outer side of the spout at its lower end, as shown in Figs. 1 and 3. The dust upon passing upwardly around the lower edge of the spout strikes the shield and is defiected laterally below the face of the attendant, thereby enabling the machine to be handled without interference of the dust.

The shavings are preferably supplied continuously to the feed-spout, so as to avoid stopping and starting of the supply-conveyer. In

order to cause the shavings to accumulate in the feed-spout and prevent the same from escaping. atthe lower end thereof while the spout stantly-incoming shavings to fill the spout.

After the previous charge of shavings has been baled and discharged from the press the lower section of the spout is again moved from the stop-board to the box, whereby the flow of shavings from the spout into the box is resumed. The lower end of the movable spoutsection stops short of the stop-board, so as to form a small gap between the same, as shown in Fig. 1. This relative arrangement of the spout and stop-board, while attended by a slight waste or spilling of the shavings, per- Inits of shifting the spout easier than if the parts were fitted to produce-a perfect closure of the spout when the same is swung away from the .presser-box. By accumulating the shavings in the spout while the bale is being pressed a large quantity of shavings is always on hand, which permits of filling the box rapidly.

The conveyer shown in the drawings for carrying the shavings from the storage-room to the feed-spout consists, essentially, of an inclined elevator leg or housing q, an endless chain belt q, arranged lengthwise in the leg and passing around wheels Q2 g at the lower and upper ends of the leg, and wings or flights q, secured transversely at intervals to the belt. The lower side of the elevator-leg communicates at a distance from its upper end with the upper or receiving end of the feed-spout, and the belt is driven so that the lower or carrying part thereof moves upwardly along the lower side of the leg, whereby the shavings are carried from the storageroom into the feed-spout. The upper or return part of the elevator-belt is supported on a board g in the elevator-leg and may extend at its upper end close to the upper wheel g but its lower end is separated a considerable distance from the lower wheel so as to form an opening g, through which the shavings can drop to the lower carrying side of the ele- Vator, thereby avoiding the tendency of choking the elevator, which would be liable to happen if all the shavings had to passunder the lower wheel g Between the feed-spout and the upper wheel Q3 the elevator-leg is provided in its lower side with a relief-opening o. The shavings elevated by the lower part of the conveyer-belt q are discharged into the feed-spout until the same is filled, and then the surplus is carried beyond the feed-spout BEST AVAlLABLE CG? and discharged through the reliefropening in the elevator-leg, thereby preventing choking of the elevator. As the shavings are discharged from the spout into the presser-box and a vacant space is formed in the top of the spout, all of the shavings carried by the elevator are again discharged into the spout until the same is filled, and then the surplus is carried to the relief-opening.

IV represents a return-conveyer whereby the surplus shavingscarried beyond the feedspout are returned to the storage-room. This conveyer consists of a leg or housing w, extending from the delivery end of the supply-conveyer Q into the shavings storeroom, and an endless belt w, passing around wheels 20 0 at opposite ends of the return-leg w and proover a board 00 in the return-leg. The surplus shavings discharged through the reliefopening of the elevator-leg q are conducted by a chute X upon the board w from which they are carried by the return-belt into the storage-room. By thus returning to the storage-room the surplus shavings, which at times cannot enter the feed-spout, the conveyer mechanism may be run continuously without liability of clogging the same.
